Allow plugins to define change search operators.

Create a DynamicBuilder interface in the QueryBuilder class along with
supporting methods and enhancements to support defining dynamic search
operators that can be altered for each query build.  Despite allowing
for dynamic modifications, the QueryBuilder class was kept generic.  No
imports or dependencies on other Gerrit frameworks such as plugin logic
were added to the QueryBuilder.

Enhance the ChangeQueryBuilder to use a DynamicSet to define
DynamicBuilders so that plugins can define search operators.  Plugins
can define DynamicBuilders and bind them to the DynamicSet on load.
Plugin search operators are defined similarly to the way
ChangeQueryBuilder operators are defined, by annotating methods in the
DynamicBuilder with @Operator.  The name of the annotated method
determines the name of the search operator.
